Typo Found in Kryptos CIA Sculpture
SimuAndy writes "Elonka Dunin, game developer at
Simutronics and author/editor of the
new book, 'The Mammoth Book of Secret Codes and Cryptograms', reports that what everyone had thought was the answer to part 2 of the CIA's encrypted
Kryptos sculpture, wasn't. Sculptor Sanborn announced this week that everyone had gotten it wrong, because of a mistake on the art piece.
For more info, check out the
Wired story, or the
Kryptos Group announcement."
The problematic part is at the end of part 2: "... forty-four seconds west. ID by rows." On April 19th, sculptor Sanborn contacted one of the Kryptos Group moderators to say, "No, that last part is wrong." He also indicated that there was a missing character on the sculpture, probably something that would have resulted in a plaintext "X" before that section. He said that he had thought that with the missing character, the section in question would have come out to be an unintelligible scramble. Instead, he was astounded to see that by sheer chance, the resulting random text had turned out to be apparently intelligible English, "ID BY ROWS", although that was not what was intended.
what are the odds of that?
It's not a "typo". According the wired article, Sanborn decided to leave out a single charater (an "x" serving as a "period") for asthetic reasons and this led to a faulty decryption of one phrase of the message.
.. when I was taking Operating Systems II, and our first homework questions was to decrypt the encrypted assignment once we wrote a public-private de/encryption program, using the public & private keys we were given. Shortly after I got my program written & debugged, I figured out that the teacher had used/given out a wrong number (!), meaning the assignment couldn't be decoded, so I told my buddy who was also in the same class with me before the weekend so he didn't have to waste his time as well.
;-)
The following week in class the teacher announces the correct public & private keys, and most of the class flipped out since they had spent the time trying to figure out why their program wasn't decoding the encrypted assignment. (I guess those students never used a test case to verify that their program _actually_ was working correctly!?)
I guess it pays to pay attention to the expected data.
